To all 'whom if may concern.'

Bc it known that I, EMMANUEL Anonim- SALvAToR, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of Few York, have invented certain new and esenl Improvements in Means for Indicating and Recording the Revolutions of Marine Ei'isines; and l do hereby' t 1 declare the falen-:inv to be a full, clear, and

ie exact description ofs the invention, such as will enable others skilled in the art to which it anpertains o make and use the. same.

It v invention relates primarily to means for maintaining a predetermined speed of wat vessels, siii-h as battle-ships, cruisers snd the like in maneuvers or target practice, to prevent the shi s losing their proper position in the ine unil prevent collision.

The invention consists in devices for the purpose as ill be fully disclosed in the folowing specification and claims.

In the accompanying drawings, which form part of this specification:-Figure 1 represents a side elevation partly in section of mechanism embodying my invention. Fig. 1a a side elevation of therovolution indicator with part of the case broken away. Fig. 2 a top pian view, partly broken away, of means for operating the revolution indi- SG cater, the indicator being removed. Fig. 3 e vertical transverse section on line 3, 3, Fig. 2, partly in elevation. Fig. 4 a top plan view of the revolution indicator. Fig. 5 e horizontal section of the revolution indicater. Fig. 6 s top plan view showing the niet ns for enga i g and discngagiiig the worin gear. Fig. 7 an end View showing the same Fig. 8 an end view of thc mechanism, anti revolution indicator partly in section showe inv the recording niechanigin.

Reference g had to the .lrawings and :ne designar characters thereon, the numeral 1 init stes the case of the. engine f' 2 a shaft sixpported in revolution indL and extending through the case and has secured thereon series of disks 3 graduated in diameter provided with lperipheral the largest diskto GO teeth on the 'smallest sk shown, number of teeth on each sk corresponding with the revolutions of he engine per minute; that is to say, when he largest disk connected, t'he engine is onninfr at 94 revolutions per minute, and then t,\e smsl'esst disk is connected the engine is running et revolutions per minute.,-

. the yoke 19, by links .25. 25.

worm teeth 4, which vary from 94 teeth on' 5 indicates a revolnble shaft f provided1 with worm teeth 6, which engage the several disks 3, is supported in a yoke 7 having arms R, 9, which engage a shaft. 10, and between 60,-

4gear 70 and the arm-9, which gear engages a xke I gear 15 on the shaft 5 to revolve said shaft, and the disks 3.

16 is a bevel gear on the end of shaft l, which engages a bevel gear 17 on a shaft 18 75 which is connected by intermediate shafts with the main shaft of the engine (not shown) to take its speed therefrom.

The shaft 5 and its yoke 7 swing vertically on the shaft 10 to engage and disengage the" 80 worin gear', and the free end of the shaft 5 engages a slotted yoke 19 the'length of the space occupied by the disks 3, is ralsed by the lever 20, t ie chain 21 passing over sheaves 22, 22 and 23 and is'connected to lever 23 35 on shaft '24, and the shaft 24A is connected to After the shaft 5 has been shifted to the desircd disk 3, the shaft 5 is brought into operative engagement with the disk by springs "26, 16, and the shaft ,90 5 is locked in engagement with, the disks 3 by a rack 24 havin" projecting fingers 25 between which the s eeve 26 on the shaft 5 lies. The spaces between the fingers 25 are nnm' bered, as shown in Fig. l, to corres ond with 95. the disk 3 with which the shaft 5 is in engagement. The rack 2t being outside of the casing l, and the shaft extending through the casing and the rack 24', the engineer can readily see the position of the shaft 5 and by. 190 the numerals under the spaces between the fingers, he is apprised of the number of revo'- lutions of the engine that are required by the' oliicer on dec-k or on the brid e. t

On the shaft 2, carrying tie disks 3 is a 105 bevel gear 27, which eno'agcs alike bevel ear 'J8 provided wit-ha hol ow shaft, 29 on w ich' is a hand 30, -and through the shaft 29 pro- `ects a shaft- 29 from a clock,`(not shown) ear-ing the second hand 30 of the clock, and 119 both hands revolve over a dial 31 which may be separated into spaces representingv seol i i i i l i ends. The graduated scale on the dial may however be dispensed with, as the engineer with a worm gear of 3/8 of an inch pitch, to engage a worm gearV Wheel 36 having 2O teeth on its` perimeter, and integral with saidV wheel 36, or connected thereto is a recording wheel 37, having nui'nbers on its periphery, in this instance running from G0 to 94, to correspond with the graduation of the disks 3.

38 is a hammer pivored on a post 39 and having a spring 40 on the upper end of the bar 39 which engages the arm 41 of the hammer and forcibly drives it down, and on the opposite end of the arm 41, is a pivoted latch 42, which is engaged by a toe or projection '13 on the yoke 19,' and as the yoke rises the up- -ward swing of the latch 42 allows the toe to pass it, but as the voke descends, the toe strikes the latch and raises the hammer 38 which is instantly forced down by the spring and record-sthe number on the Wheel 37 on a strip of aper 43 graduated into hours, minutes ant seconds, not shown. The pa per is supplied from a. roll 44, passes over rollers 45, 46, 0n top of the wheel 37 and under the hammer 38, and is drawn by it friction roll x17 operated by a clock 4S, in the usual manner.

49 indicates a. case or stand designed to rest on the bridge,`the position of the coinmanding otlicer, while maneuvering, in target practice or 'in actual engagement. -'ithin the case is a horizontal disk o() having a worin gear 51 on its periphery, and is rotated b Y a shaft 52 having a worm gear 53 thereon Awhich engages the gear 51, through the n'iedium ofa crank 54, and is operated by the commanding ollicer. In the upper surface of the disk are a series of holes 55, thirty-five in number corresponding with the number of disks 3 in the revolution indicator, 56 is a pin to engage seid holes 55, to'lock the disk in any predetermined position. rlhe pin 56 is connected to a lever 57 pivotally supvported on a. post 58 ou the cover 59 of the gaging a collar 62 on the pin.

casing and is engaged by a lug 60 on the le ver 20, to raise the pin 56 out of engagement with the holes, and the pin is returned or seated in the proper hole by a spring 61 en lhe disk 50 is. limited in its revolution either to the right or the left by a projection 63 on the upper side of the disk which engages a shoulder or stop 64, one on each side of the transverse center of the casing, to prevent the disk being moved too far to register with the locking pin 56.

The man@ 0i iiidisk 5o is'imiicaied by a. screw-threaded shaft supported in bear'- ings 65' on which a i'iut 56 is provided'with ari index finger 67 which registers with'a graduated scale 68, extendimr from to 04 to correspond with the graduated disks 3 of the engine revolution indicator. The shai t provided with a gear wheel 69, -which engages a gear wheel 70 on the shaft 52 and is rotated tlrcby as the shaft`52 is rotated to change the position of the disk 50, and the shaft 5 t0 engage .the disks 3.v '.lhe lover 2Q is provided with a sector-shaped face 20" over which the chain 21 works and is supported iii bearings 21 on the top of the case 491 71 is a hollow shaft to which the disk 50 is secured and is revolved thereby, the, shaft having a collar 72 which rests on a seat 73 in the case 49, and on the lower end of the shaft is a bevel gear wheel 74 which engages a like.

bevel gear wheel 75 on one end of a hollow shaft 76, while a like lbevel gear wheel 77 at the opp'osite end of the shaft 76 engages a. bevel gear 78 on .one end of a hollow shaft 79 having a `bevel gear S0, which engages the gear 13 on shaft 12.

The ship being under the control of the oflicer on the bridge, and he desiring to change the speed of the shi i, he seizes the lever 20, with his right hand, draws it toward him which through the medium of the chain 21 and the yoke 19, disengages the shaft 5 from its disk 3, and simultaneously raises the pin 56 out of engagement with the disk 50, when with his left hand he turns the. crank 54 and revolves shaft 52 one revolution to increase or decrease the revolutions of the engine one revolution. The revolution of the disk 5() is instantly transmitted to the shaft- 12 of the .revolution indicator and the worin gear therein properly shifted. The officer then releases the .ever 20 andthe disk is locked by the pin 56 having been forced into position' b v t ic spring 61. While this change is being Vefeetod by the coiiniianding oll'icer on the bridge, the engineer on watch is instantly vof los

appriscd thereof by the hand 30 on the dial l 31, and the change in the position of the worin shaft 5 to its proper disk 3 with which it must engage to eflect the change in the revolution of the enginerequired bv the commanding oflicer. 'llie dial 31 is placed near the throttle valve so that the engineer on watch can readily scc and read the dial and mani ulate the throttle valve to supply more or rei ucc the suppl)r of steam as may be necessary to produce the number Aof revolutions of the engine required.

lt is obvious that the number of disks 3 the speed of the engine. 1n maneuvering battleships the speed never exceeds ninety four revolutions or is less than sixty revolutions, while the, speed of a cruiser could be from sixty to one hundred and twenty revolui i i i l i l l l l i l i t i l l l l l l ,revoluble propelling member adapted to engagesaid disks separately a revolnble shaft parallel with the shaft supporting the disks, supportingr and provided with means for revolving said member and on whieh said shaft member is axially and lon fitndinally movable, means for raising an( loweringr said member and means for moving the member from one disk to another.
